Cardiac disease following radiation therapy represents a major consideration in the treatment of a variety of malignancies. Damage to the heart can manifest in a variety of pathologies including ...ischemic cardiac disease, cardiomyopathy, valvular dysfunction, arrhythmias, and pericarditis. This damage has been shown to directly relate to cardiac radiation dose and to stem from a range of cellular pathways that are often related to fibrosis. The importance of minimizing radiation dose to the heart is especially critical in the pediatric population and when treating disease sites adjacent to the heart. Proton therapy represents a promising approach to minimize dose to normal tissues such as the heart. The cardiac dosimetry reductions due to proton therapy have been demonstrated in multiple cancers and further long-term follow-up will determine the clinical significance of these reductions to cardiac structures. Future approaches using advanced techniques such as FLASH therapy could provide even further benefit by reducing post-radiation fibrosis.
Physical performance limitations are one of the potential long-term consequences following diagnosis and treatment for childhood cancer. The purpose of this review is to describe the risk factors for ...and the participation restrictions that result from physical performance limitations among childhood cancer survivors who participated in the Childhood Cancer Survivor Study (CCSS). Articles previously published from the CCSS cohort related to physical performance limitations were reviewed and the results summarized. Our review showed that physical performance limitations are prevalent among childhood cancer survivors and may increase as they age. Host-based risk factors for physical disability include an original diagnosis of bone tumor, brain tumor, or Hodgkin's disease; female sex; and an income less than $20,000 per year. Treatment-based risk factors include radiation and treatment with a combination of alkylating agents and anthracyclines. Musculoskeletal, neurologic, cardiac, pulmonary, sensory, and endocrine organ system dysfunction also increase the risk of developing a physical performance limitation. In summary, monitoring of physical performance limitations in an aging cohort of childhood cancer survivors is important and will help determine the impact of physical performance limitations on morbidity, mortality, and caregiver burden. In addition, in developing restorative and preventive interventions for childhood cancer survivors, we must take into account the special needs of survivors with physical disability to optimize their health and enhance participation in daily living activities.
Abstract We aimed to evaluate the prognostic significance of traditional clinical predictors in osteosarcoma through an international collaboration of 10 teams of investigators (2680 patients) who ...participated. In multivariate models the mortality risk increased with older age, presence of metastatic disease at diagnosis, development of local recurrence when the patient was first seen, use of amputation instead of limb salvage/wide resection, employment of unusual treatments, use of chemotherapeutic regimens other than anthracycline and platinum and use of methotrexate. It was also influenced by the site of the tumour. The risk of metastasis increased when metastatic disease was present at the time the patient was first seen and also increased with use of amputation or unusual treatment combinations or chemotherapy regimens not including anthracycline and platinum. Local recurrence risk was higher in older patients, in those who had local recurrence when first seen and when no anthracycline and platinum were used in chemotherapy. Results were similar when limited to patients seen after 1990 and treated with surgery plus combination chemotherapy. This large-scale international collaboration identifies strong predictors of major clinical outcomes in osteosarcoma.
Health related quality of life (HRQL) assessments during therapy for pediatric cancer are important. The objective of this study was to describe reasons for failure to provide HRQL assessments during ...a pediatric acute myeloid leukemia (AML) clinical trial.
We focused on HRQL assessments embedded in a multicenter pediatric AML clinical trial. The PedsQL 4.0 Generic Core Scales, PedsQL 3.0 Acute Cancer Module, PedsQL Multidimensional Fatigue Scale, and Pediatric Inventory for Parents were obtained from parent/guardian respondents at a maximum of six time points. Children provided self-report optionally. A central study coordinator contacted sites with delinquent HRQL data. Reasons for failure to submit the HRQL assessments were evaluated by three pediatric oncologists and themes were generated using thematic analysis.
There were 906 completed and 1091 potential assessments included in this analysis (83%). The median age of included children was 12.9 years (range 2.0 to 18.9). The five themes for non-completion were: patient too ill; passive or active refusal by respondent; developmental delay; logistical challenges; and poor knowledge of study processes from both the respondent and institutional perspective.
We identified reasons for non-completion of HRQL assessments during active therapy. This information will facilitate recommendations to improve study processes and future HRQL study designs to maximize response rates.
Health related quality of life (HRQL) assessments during therapy for pediatric cancer provide valuable information to better understand the patient experience. Our objective was to determine the ...impact of a patient-reported outcome (PRO) coordinator on HRQL questionnaire completion rates during a pediatric acute myeloid leukemia (AML) trial.
AAML1031 is a multicenter Children's Oncology Group therapeutic trial for de novo AML with a secondary aim to assess HRQL of children and adolescents treated with chemotherapy and hematopoietic stem cell transplantation (HSCT). Parents/guardians are the primary respondents and four questionnaires are administered at eight time points. The questionnaires are the PedsQL 4.0 Generic Core Scales, PedsQL 3.0 Acute Cancer Module, PedsQL Multidimensional Fatigue Scale, and the Pediatric Inventory for Parents. To improve response rates, a central PRO coordinator was instituted and reminded sites about upcoming and delinquent questionnaires. The proportion of HRQL questionnaires completed were compared prior to, and following institution of the PRO coordinator. This analysis evaluated the first five assessment time points.
There were231 families who consented to participate in the HRQL aim. Overall response rates for all questionnaires were 73-83%. At time point 1, within 14 days of chemotherapy initiation, post-PRO coordinator completion rates were significantly higher for three of four questionnaires. However, the effect was not sustained and at time point 4, one month following last chemotherapy or HSCT, completion rates were significantly lower post-PRO coordinator for all four questionnaires.
Addition of a central PRO coordinator did not result in sustained improvement in HRQL questionnaire completion rates. Efforts to improve response rates must consider other strategies.
Introduction
Objectives were used to describe guardian proxy‐report and child self‐report quality of life (QoL) during chemotherapy for pediatric acute myeloid leukemia (AML) patients.
Methods
...Patients enrolled on the phase 3 AML trial AAML1031 who were 2‐18 years of age with English‐speaking guardians were eligible. Instruments used were the PedsQL Generic Core Scales, Acute Cancer Module, and Multidimensional Fatigue Scale. Assessments were obtained at the beginning of Induction 1 and following completion of cycles 2‐4. Potential predictors of QoL included the total number of nonhematological grade 3‐4 Common Terminology Criteria for Adverse Event (CTCAE) submissions.
Results
There were 505 eligible guardians who consented to participate and 348 of their children provided at least one self‐report assessment. The number of submitted CTCAE toxicities was significantly associated with worse physical health summary scores (β ± standard error (SE) −3.00 ± 0.69; P < 0.001) and general fatigue (β ± SE −2.50 ± 0.66; P < 0.001). Older age was significantly associated with more fatigue (β ± SE −0.58 ± 0.25; P = 0.022). Gender, white race, Hispanic ethnicity, private insurance status, risk status, bortezomib assignment, and duration of neutropenia were not significantly associated with QoL.
Discussion
The number of CTCAE toxicities was the primary factor influencing QoL among children with AML. Reducing toxicities should improve QoL; identifying approaches to ameliorate them should be a priority.
Little is known about quality of life (QoL) in pediatric acute myeloid leukemia (AML) patients. We found that fatigue was prominent during AML therapy; the number of toxicities submitted was the primary factor influencing QoL while sociodemographic factors were not associated with worse outcomes. These findings suggest that fatigue and toxicity reduction are important areas for future research.
The past four decades have seen tremendous progress in the treatment of pediatric and adolescent cancers. As a consequence, there are increasing numbers of adult childhood cancer survivors. This has ...prompted investigation into the long-term consequences of cancer treatments. One group that merits special study is the survivors of lower-extremity bone tumors. Their function and quality of life may depend in part on both the surgery and the age at which it was performed. Comparisons between studies are difficult because small numbers of patients and the use of varying research designs and methods have limited research in this area. The purpose of this article is to review the major surgical approaches to lower-limb bone tumors and their impact on pediatric patients. The results show that survival is equivalent between amputation and limb salvage. Complications occur more frequently in limb salvage. The long-term outcomes of those undergoing amputation and limb salvage have not been found to be substantially different in regard to quality of life. In conclusion, prospective long-term follow-up of pediatric patients with lower-limb tumors is needed to (1) determine in a uniform manner the long-term complications, quality of life, and functionality of this population and describe differences within this patient population based on age at diagnosis and surgical procedure, (2) identify areas of concern that are amenable to intervention, and (3) provide clinicians and future patients a better understanding of the surgical options.
